What is the mode of transmission of Giardia lamblia?
What is the mode of transmission of Giardia lamblia?
Giardia spreads easily and can spread from person to person or through contaminated water, food, surfaces, or objects. The most common way people get sick is by swallowing contaminated drinking water or recreational water (for example, lakes, rivers, or pools).
How is Giardia transmitted from animals to humans?
How do you get giardiasis and how is it spread? You can get giardiasis if you swallow the Giardia parasite (germ). Giardia—or poop from people or animals infected with Giardia—can contaminate anything it touches. Giardia spreads very easily; even getting tiny amounts of poop in your mouth could make you sick.
Can you transfer Giardia?
People can spread the Giardia parasite even if they do not have symptoms. ➢ Pets can also be infected and can spread Giardia to you through their feces. ➢ Giardia is NOT spread from one person to another by coughing or sneezing, sharing drinks, hugging or kissing.
Is Giardia direct transmission?
Transmission of giardiasis occurs through the faecal-oral route, and may be either direct (i.e., person-to-person, animal-to-animal or zoonotic) or indirect (i.e., waterborne or foodborne).
What is the incubation period for giardia in humans?
Acute giardiasis develops after an incubation period of 1 to 14 days (average of 7 days) and usually lasts 1 to 3 weeks. Symptoms include diarrhea, abdominal pain, bloating, nausea, and vomiting. In chronic giardiasis the symptoms are recurrent and malabsorption and debilitation may occur.
Where is giardia most commonly found?
Giardia parasites are found in lakes, ponds, rivers and streams worldwide, as well as in public water supplies, wells, cisterns, swimming pools, water parks and spas. Ground and surface water can become infected with giardia from agricultural runoff, wastewater discharge or animal feces.
Can humans get Giardia from dog saliva?
Can I get Giardia infection from my pet? The chances of people getting Giardia infection from dogs or cats are low. The type of Giardia that infects humans is not usually the same type that infects dogs and cats.
What kind of disease does Giardia lamblia cause?
Giardia lamblia(syn. Giardia intestinalis, Giardia duodenalis) is a flagellated unicellular eukaryotic microorganism that commonly causes diarrheal disease throughout the world. It is the most common cause of waterborne outbreaks of diarrhea in the United States (18) and is occasionally seen as a cause of food-borne diarrhea (47a, 227).
Is the Giardia duodenalis a zoonotic infection?
Giardia duodenalis (syn. Giardia lamblia and Giardia intestinalis) is a common intestinal parasite of humans and mammals worldwide. Assessing the zoonotic transmission of the infection requires molecular characterization as there is considerable genetic variation within G. duodenalis.
What kind of animals do Giardia live in?
This comprises Giardia agilis in amphibians, Giardia ardeae and Giardia psittaci in birds, Giardia microti and Giardia muris in rodents, and Giardia duodenalis in mammals. Another species, Giardia varani, has been described from a water monitor ( Varanus salvator) ( Upton and Zien, 1997 ).
